This handbook is a guide that can be used as a first step
when configuring a truck. It allows the user to examine
options and variables that affect performance of the driveline and frame.
Trucks are highly configurable machines. There are
numerous choices for every major component (frame,
engine, transmission, tires, axles, suspension, gear ratios,
etc.). It’s critical not to over or under spec a truck for an
application. A well spec’d truck is typically a balance
between variables like cost, GVWR, maximum speed,
gradeability, startability, and fuel economy. There are
also intangibles like driver preference, serviceability,
and customer history to consider.
The equations and methodology in this handbook are
provided to help select components and predict how
they will work together to create a truck with the desired
level of performance.
Time spent investigating the customers needs is critical for creating a well configured truck that will meet or
exceed customer expectations. Normally, experts with
years of experience and/or classroom training perform
this type of work.

Weight Distribution
WEIGHT DISTRIBUTION
The first step in spec’ing a Truck is to understand
how the load is distributed on the Front and Rear Axles.
The load is defined as the Maximum expected weight
of a fully loaded Truck. That includes the Driver, Fuel,
Fluids, Payload, and Truck Body. Once the axle loading is known, it’s possible to begin selecting the Frame,
Engine, Transmission, Axles, Suspension, Tires, etc.
Center of Payload and
Body or 5th wheel location
Center of
Tandem Axle
Attachment
Weight
Start by identifying where (in relation to the axles) the
load will come onto the truck. This can be a 5th wheel
location, or the center of gravity of the Body and Payload
(like a Dump Truck or Tanker). See above illustration.
Axle Loading can be found by adding up how major
loads are distributed on each axle. Typical loads are
the weight of the Truck Chassis, Body, Payload, or 5th
wheel. Add up all the loads that apply for your Truck.
Axle Loading Due to Truck Chassis
(see “Chassis Types” tables in this section)
Front Axle Load (Given by Caterpillar) = _______ lb
Rear Axle Load (Given by Caterpillar) = _______ lb
Axle Loading Due to Body and Payload
(omit if using a 5th wheel)
Front Axle Load = (Body + Payload weight) × (A/WB)
= _______ lb
Rear Axle Load = (Body + Payload weight) × (B/WB)
= _______ lb
On-Highway Trucks
Axle Loading Due to 5th Wheel
(omit if using a Body)
Front Axle Load = 5th Wheel Load × (A/WB)
= _______ lb
Rear Axle Load = 5th Wheel Load × (B/WB)
= _______ lb
Axle Loading Due to Forward Mounted Loads
(Winches, Plows, etc.)
Front Axle Load = Attachment weight × (C + WB)/
WB = _______ lb
Rear Axle Load = – Attachment weight × (C/WB) =
–_______ lb Negative
Lift Axle Force*
*Max Lift Force = Lift Axle (Rated Capacity) – Weight
of the Lift Axle.
Example:
Max lift force for a 13,200 lb lift axle is approximately
12,000 lb. The remaining 1200 lb is the weight of the
axle, tires, wheels, and brakes.
Axle Loading Due to Lift Axles*
(see above illustration)
Front Axle Load = – Lift Axle Force × (E/WB) =
–______ lb Negative
12
Rear Axle Load = – Lift Axle Force × (D/WB) =
–______ lb Negative
*If more than one (1) lift axle repeat as required.
Total Axle Loading
Front Axle Load = Add all Front loads that apply =
______ lb
Rear Axle Load = Add all Rear loads that apply =
______ lb

GVWR and GCWR
GVWR AND GCWR
GVWR = Gross Vehicle Weight Rating. This rating
is used for a Straight Truck.
GCWR = Gross Combination Weight Rating. This
rating is used for Tractors with 5th wheels.
Procedure to Determine GVWR or GCWR
1) Determine the maximum expected load on each
axle (see Weight Distribution section).
2) Select Axles, Suspensions, Brakes, Wheels and
Tires that are sized to take the load predicted by
the Weight Distribution Study. All components
must be rated equal to or greater than the expected
axle loading. See Appendix D, E, F, H, I, J, K, and
L for component ratings.
3) The lowest rated component for each axle (including the axle), is the Maximum Axle Rating for
that axle.
GVWR = Front + Rear + Lift (Axle Rating for each
axle)
GCWR = Front + Rear + Lift + Trailer (Axle Rating
for each axle)
12-14
Example: Front Axle Rating
Expected Front Axle Load
12,420 lb
Axle rated for
13,200 lb
Suspension rated for
14,000 lb
Wheels rated for
14,000 lb
Tires rated for
13,800 lb
Brakes rated for
14,000 lb
In this example the front axle is the lowest rated component that will carry the load predicted by the Weight
Distribution Study. Thus, the Front Axle Rating is
13,200 lb in this example.
Bridge Laws
Careful attention must be given to laws governing
overall weight, maximum axle loading, and axle spacing.
These laws are commonly referred to as Bridge Laws,
and are different in every State, Region, or Province.
This handbook does not cover these laws. The reader
is advised to refer to their local Bridge Law formulas.

Frame Selection
On-Highway Trucks
FRAME SELECTION
Based on Front Axle Load, Desired GVWR and
Wheelbase: Select a Frame from table below. Frame
length varies in roughly two inch increments to accommodate many different body sizes. Frames can also be
Reinforced (or Doubled) to carry heavier loads (see
illustration on next page).

ENGINE SELECTION
Step 1 Calculations: Add up the HP required at the expected
vehicle cruise speed.
There are many factors that dictate the correct engine
size for a specific application. It’s possible to use a
mathematical approach to add up all the horsepower
demands to size the engine. However, it’s also important to understand the application and driver habits. In
addition, understand how the customer’s other trucks
are configured. This critical customer knowledge is
used to verify or modify the results of the mathematical
approach to achieve the best engine selection for the
application.
NOTE: All the following formulas can be programmed
into a Spread Sheet for faster evaluation.
Rolling Resistance: The HP required on a flat surface
to overcome Tire Squat. Since tires
are not perfectly round, (especially
when loaded) the Truck is climbing
a small slope just to move forward.
Pr =
Mathematical Approach Overview: 3 step process.
1) Add up all the HP loads at vehicle cruise speed.
Examples of HP demands are: Rolling Resistance,
Drag, Slopes, Road Surface, Driveline Losses,
Accessories, and Power Takeoffs.
2) Determine the Torque required to start fully loaded
on the customer’s maximum grade. This is called
(Startability).
3) Use your knowledge of the application to verify if
the Engine selected in steps 1 and 2 makes sense.

Engine Selection
Step 2A: (Manual and Automated Manual Transmissions) Verify the Engine selected in Step 1 can
get the Truck moving on the customer’s maximum grade.
Startability: Is the ability of the truck to start moving on
the steepest grade the driver will face. The
equation below (S) calculates the Theoretical Maximum Percent grade for the Engine
you selected in Step 1. To more accurately
predict Startability, ground conditions must
be considered. Subtract the effects of ground
conditions from (S) to determine the Maximum Predicted Startability.
S=
(Tc × R × M)
(10.7 × GW)
Tc = Fully Developed Torque (from Engine selected in
Step 1). See Engine Specification table.
R = The overall Driveline gear ratio.
Transmission (low gear) × Axle × Aux Trans × Drop box
Omit Aux Trans and Drop Box ratios if not used
M = Tire Revolutions per mile. See Appendix I.
GW = Desired Gross Vehicle Weight or Gross Combination Weight.
On-Highway Trucks
Step 2B: (CX31 Automatic Transmission) Verify the
Engine selected in Step 1 can get the Truck moving on the customer’s maximum grade.
Startability: Is the ability of the truck to Start moving on
the steepest grade the driver will face. For
an Automatic Transmission a simple equation cannot be used to predict Startability.
For the CX31, see the Startability chart
in Appendix G. It assumes starting on the
best concrete. To more accurately predict
Startability, ground conditions must be
considered. Subtract the effects of ground
conditions from (S) to determine the Maximum Predicted Startability.
S = See Appendix G
Ground Conditions: See Tire Pavement Factors table or
Subtract 6% for every inch of tire
penetration.
Maximum Predicted Startability
= S – Ground Conditions
Startability must be equal to or greater than the customer’s maximum percent grade. If below Maximum,
Select an Engine with equal or greater HP and Higher
Fully Developed Torque from Engine Specifications
table. Rerun the Startability calculations to verify.
10.7 = Constant.
Ground Conditions: See Tire Pavement Factors table or
Subtract 6% for every inch of tire
penetration.
Maximum Predicted Startability
= S – Ground Conditions
Startability must be equal to or greater than the customer’s maximum percent grade. If below Maximum,
Select an Engine of equal or greater HP with Higher Fully
Developed Torque from Engine Specifications table.
Rerun the Startability calculations to verify. Continue
to Step 3 for final Engine selection.
12
Step 3: Final Engine Selection. In Steps 1 and 2 you
selected an Engine that had enough HP to maintain cruise speed and start on the maximum grade.
Before making the final Engine selection, factor
in application and driver habits. For example,
additional Torque may be required in mountainous regions. Perhaps a smaller Engine can be used
to save fuel if the driveline gearing is modified.

Driveline Braking
DRIVELINE BRAKING
Driveline Braking is used to augment the main service
brake system. A technology called Engine Compression
Braking allows the engine to remove horsepower from
the driveline by compressing air. In addition to providing additional stopping power, driveline braking also
reduces maintenance costs by prolonging the life of
brake linings. This technology is often referred to in the
industry as a “Jake Brake.”
NOTE: Engine Compression Braking is recommended
for all CT660 driveline braking applications.
